0x04: 8 ch Taguchi terminal connector




Please see the e-nose project page for an elaborate description as well as practical examples.


This PCB connects to an eight channel Taguchi gas sensor array (see design 0x00) and breaks out sensor excitation voltages (heater voltages, VH) and sensor voltages across load resistors on the sensor array (VRL). This way you can connect the Taguchi array to a low-cost data acquisition system like for instance the NI USB-6008 and analyse measurement data in the powerful programming environment LabVIEW.
